Chopped Basalt Fiber

In order to study the basic mechanical properties of basalt fiber reinforced recycled aggregate concrete, the concrete mix ratio, the length and the volume mixing ratio of chopped basalt fiber yarn are designed for changing factors. A total of 324 specimens have been completed for this investigation. The compressive strength, splitting tensile strength, elastic modulus and axial compressive strength of basalt fiber recycled concrete have carried on the experimental study and theoretical analysis as 81 specimens, respectively. In all specimens, coarse aggregate were replaced by recycled aggregate with a replacement rate of 100%. Experimental results show that the failure process and failure pattern of basalt fiber recycled concrete and ordinary concrete are similar; With the improvement of concrete strength grade; When the volume mixing ratio of chopped basalt fiber yarn is 0.2%, the mechanic performance can effectively improve, and the length of chopped basalt fiber has less effect on the mechanical indexes; The conversion relation between common concrete mechanics index is no longer suitable for basalt fiber recycled concrete, new conversion formulas for basalt fiber recycled concrete between the mechanics index were presented through fitting experimental data.

Chopped Basalt Fiber

Wood composite is weak under heavy loadings, which was improved by reinforcing basalt fibres. In this study, chopped basalt fibres with different lengths (5mm, 10mm, 15mm and 20mm) were mixed with fir sawdust at 2.5%, 5%, 7.5% and 10% weight fractions to produce basalt fiber reinforced fir sawdust panels. The reinforced panels showed improved strength values. A maximum bending strength value of 44.1 MPa was obtained when the mean length of chopped basalt fiber was 15mm and the weight fraction was 2.5%. The tensile strength reached a maximum value of 17.4MPa when the mean length of basalt fiber was 10mm and the weight fraction was 10%. Compared with the unreinforced fir sawdust panel group, the reinforced panel group increased bending strength 60.7% and had a 47.5% increase in tensile strength. These findings demonstrate that basalt fibre has very promising prospects for strength improving.

Chopped Basalt Fiber

Experimental studies on basalt fiber have been performed in China and abroad. Specifically, the compressive properties, flexural properties, splitting tensile properties and impact test behavior of chopped basalt fiber-reinforced concrete have been investigated. In addition, the effects of the mixing amount of fibers on the mechanical properties of C30 concrete were scrutinized, and the best mixing amount of fibers was obtained. The results indicate that the static and impact test behaviors of basalt fiber reinforced concrete significantly improved, and strengthening and toughening effects were achieved.

This paper studies on the influence of impermeability in basalt fiber of C50 concrete, and the result was compared with the same dosage of polypropylene fiber. Experimental test show that after incorporating basalt fiber and polypropylene fiber concrete impermeability resistance were significantly improved, the impermeability of polypropylene fiber is superior to basalt fiber.

Research Situation

The current research situation of basalt fiber reinforced concrete was analyzed on the basis of the previous research results. When concrete is incorporated with basalt fiber, the compressive performance of concrete is instable, the tensile strength changes along with the fiber content, but the durability improves significantly , and the bending performance and impact resistance has more obvious improvement. According to the characteristics of chopped basalt fiber reinforced concrete, the prospect of the application of basalt fiber reinforced concrete is explored.
